Abercraf transmitting station

The Abercraf television relay station is sited on high ground to the east of the village of Abercraf in the upper Swansea Valley, though it is actually closer to Coelbren than to Abercraf itself. It was originally built in the 1980s as a fill-in relay for UHF analogue colour television covering the communities of Abercraf, Coelbren, Penycae and Ynyswen. It consists of a 45-metre self-supporting lattice mast standing on a hillside which is itself about 270 metres above sea level. The transmissions are beamed southwest and northwest. The Abercraf transmission station is owned and operated by Arqiva.
Abercraf transmitter re-radiates the signal received off-air from Carmel about 12 miles to the west. When it came, the digital switchover process for Abercraf duplicated the timing at Carmel with the first stage taking place on 26 August 2009 and with the second stage being completed on 23 September 2009. After the switchover process, analogue channels had ceased broadcasting permanently and the Freeview digital TV services were radiated at an ERP of 18 W each.
